Question: iPhone cannot verify server identity

Today whenever I enter my e-mail on iOS 10, iPhone 7 a message pops up with 'cannot verify server identity'...previosly this gave you the option to continue, details or cancel...now on iOS 10 the continue option has been dropped so I cannot simply click and get my e-mails...does anyone know how to fix? I have searched online with no joy as all are much older versions of iOS. or based on safari issues.

So after a lot of trouble shooting this was what Solved it so I could get the Continue to be able to Trust Certificate

1st Delete the Email Account that's giving you Trouble


2nd Go back to Settings and then Mail then Click on Accounts then click on another email account that you have on there click on it then Outgoing Mail Server

After getting to the Outgoing Mail Server Click on the Email that you deleted in 1st step then Scoll down and

Hi

I have this problem resolved.

Affected iphone 6 ios 10.1.1

Not affected iphone se 10.1.1


Exchange 2003 self signed cert


Attempts to repair

Reset network settings - no luck

Reset all settings - no luck

Restore phone from backup - no luck

4 hours with apple support, up to senior uk advisor. No answer just that they had not seen this problem before and I appeared to be the only person with this problem so its not a bug !!!!


Every time verifying details had certificate warning but no continue button just option for cancel and details.

Iphone SE prompted for certificate warning but had options for cancel, details and continue.


This has something to do with the ssl security settings / certificates but this fix works.


So on first page of add exchange account add email and password as normal. This brings you to second page.

KEY change your email address to name@externalipaddress not name@domain.com then add the server IP in the box. Leave domain blank. Add your username as just "name" not "name@domain.com" . Thats the login name for your exchange account not your email address. You will then get the certificate warning but now you will have a continue button that was missing before. Just continue and this should work and get all ticks. If you have problems sending mail go back and add the domain in the correct field.


This is an unusual way to make the settings work but then when i go back and check the exchange account settings ios has changed the email from name@externalipaddress to the correct setting name@domain.com.


So i think this is a bug and would like to hear from apple why this works but dont think i will ever get an answer.


Hope you get working.

I have the same problem. Updated to iOS 10.1.1 Wednesday. Mail worked fine.


Then my service provider updated their certificate Friday and sinne then no go with mail. No way to accept the new certificate. There is nothing wrong in certificate itself - it is from accepted root provider in Apples list. An iPad with older iOS is fine with it. So this has to be a bug with current iOS.


I would really like to find a solution for this. Would hate to have to change for another phone because of broken mail.

PARTIALLY SOLVED: Problem started with iOS 10.1.1. I upgraded to 10.2 with no impact. Turning WIFI off and accessing mail via cellular on iPhone activates "continue" option, solving the issue for me. Problem did not reoccur when reactivating WIFI, seeming to solve the problem. I have the same problem on my iPad, (iOS 10.2). As I don't have cellular service, I have been unable to resolve this on the iPad.


This is an Apple bug. Not providing "Continue" option on "Cannot verify server identity" when connected via WIFI. Hope this solves the issue for all iOS devices with cellular service. Spread the word if this works for you.

Hi GolfProAL,


I understand that you're no longer able to access your email on your iPhone due to a dialog that appears, despite having been able to dismiss this dialog in the past. This dialog indicates that there may be a certificate issue with your e-mail provider's mail server, or there may have been a change to their systems at some point recently. As a first step, I'd try removing the account and setting it back up via the steps outlined below.
  1. On your computer, sign in to your email provider’s website to verify that all of your email is there or check if your email is saved somewhere other than your iOS device.
  2. On your iOS device, tap Settings > Mail, Contacts, Calendars.
  3. Tap the email account you want to remove.
  4. Tap Delete Account.
  5. Add your account again.

If, at that point, you're still getting the message regarding the server's identity, the next step would be to contact your email provider.

  • Contact your email provider or check their status webpage to see if they’re experiencing a service outage.
  • Ask your email provider or system administrator if you have any security features or restrictions, like two-step verification, turned on for your email account. You may need a special password or need to request authorization from your email provider to send and receive email on your device.
  • Check your email account settings with your email provider or system administrator to make sure that they're correct.

Also experiencing this problem with my iPhone 6s with iOS 10.1.1 and 10.2, connecting to an IMAP server running Postfix and Dovecot and using TLS for both.


Problem began after updating SSL certificate issued by CAcert. Note that CAcert is not listed in the default iOS root certificates, but is installed as a Profile. This combination has always worked before.


I tried deleting the mail account, rebooting the iPhone 6s, and re-setting up the email account. No go with iOS 10.1.1. Updated to iOS 10.2 and repeated email account setup. Incoming server Cannot Verify Server Identity dialog did have the Continue button this time, but outgoing (SMTP) server only gives me Details and Cancel option, no Continue option.


Server log shows that a TLS connection was established, but it then times-out after a while, waiting on the iPhone...


Is there any way to get the outgoing server Cannot Verify Server Identity dialog to give a Continue option?

I figured this out for a friend having the same issue.

What you can do is launch Safari and navigate to the https url of the server address.

Eg. https://my.server.com

You will be prompted with a security warning here and can press details then 'Trust' at the top right corner.

Close Safari and run through email wizard again (or just reenter password if account already saved) and you will again have the option to press continue for this server.

Same problem here. "Cannot Verify Server Identity" and no button anywhere to hit accept or continue.

Used my server for years, never had a problem. Came today directly after I update to 10.1.1.

I was forced to update because my WIFI refused data coming through. At least wifi works again after the update.

I had the same problem and found out that when I was on my wifi at home with Brighthouse networks I received these message. I turned off my wifi and the popups went away. I use 4 different email addresses and each mail server couldnt verify ssl certificate.
